HINGE.

SPECIFICATION forming part of Letters Patent No. 393,305, dated November20, 1888.

Application filed June 29, 1883. Serial No. 278,511. (ModeL) T0 all whomit may concern.-

Be it known that I, LOUIS HILLEBRAND, a citizen of the United States,residing in the city and county of Philadelphia, State of Pennsylvania,have invented a new and useful Improvement in Hingesand Hasps, whichimprovement is fully set forth in the following specification andaccompanying drawings.

My invention consists in the construction of a hinge or hasp havingaleaf, one end whereof is bent or curled into the form of a cylinderconstituting an axis, whereby a pintle as such is dispensed with and astrong and serviceable hinge is produced.

The invention also consists in recessing the leaf to receive a knuckleor ear which is se-- cured to the attaching-plate and embraces thecylindrical portion or axis of the leaf, thus firmly retaining said leafin position.

Figure 1 represents a face View of a hinge embodying my invention. Fig.2 represents an end view thereof. Fig. 3 represents a section on line a:m, Fig. 1. Fig. 4 represents a face view of a hasp embodying myinvention. Fig. 5 represents a section on line y y, Fig. 4.. Fig. 6representsa face view of the leaf thereof.

Similar letters of reference indicate corresponding parts in the severalfigures.

Referring to the drawings, A, Figs. 1 and 2, represents one of theleaves of a hinge, and B represents the other leaf or bottomattachingplate thereof.

The leaf A, which is constructed of sheet metal, has its inner or axialend bent into the form of a cylinder, 0, which is embraced'in part by aknuckle or car, D, the latter being riveted or otherwise secured to theplate B. The portion of the leaf A adjacent to the ear D is cut out orrecessed within its side edges, as at a, to receive the Wall of the earD and permit said leaf to rotate or turn on said ear, it being evidentthat the ear prevents disconnection of the leaf and plate.

It will be seen that the leaf A may be turned or swung on the plate 13,the cylinder 0 forming the axis of said leaf and the ear D forming thebearing for said axis; it being also seen that a pintle or rod usuallyemployed in a hinge and passed through the knuckles thereof is dispensed with and a strong and durable and servg the knuckle or ear andtherecess of the same.

In Figs. 4, 5, and 6 theimproveinent is shown as applied to ahingedlock-hasp, the swinging part of the hasp corresponding to the leaf A ofthe hinge and having the cylindrical axis 0 and bearing D therefor, thehasp being also provided with a spring for throwing out the part A, whenso desired. In this case the leaf is provided with two recesses, a a,with a neck, a, between them, as seen in Figs. 4 and 6, and the ear orknuckle D has a slot to allow theleaf to revolve the requiredextent,limited by said neck which enters the slot and acts as a stopagainst the wall thereof.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is

1. A sheet-metal hinge having a base or attaching plate, a separatearch-shaped cover or ear fastened thereto, and a leaf with a curled end,said end being encircled by said cover or car, the parts being combinedsubstantially as described.

2. A hinge or hasp consisting of a leaf with about or cylindrical endportion and a slot parallel to said cylindrical end, an attaching-plate,and a separate knuckle or ear suitably secured to said attaching-plate,said parts being combined substantially as described.

3. A sheet-metal hinge or hasp consisting of an attachingplate, a leafwith a cylindrical end portion and having slots forming a neck betweenthe same, and an ear secured to said plate and having a portion of oneof its Walls passing through said slotsin the leaf, the neck of the leafworking in a slot in said ear, said parts being combined substantiallyas and for the purpose set forth.

L. HILLEBRAND.
